Wood Chips Provide Heating to the Danish Town of Sønderborg

Low emission multifuel biomass plant

Sønderborg district heating company built a 9 MW Dall Energy Biomass system in 2014.

The biomass plant integrate several innovations of the Dall Energy Biomass concept:

  • No particlute filter, because of extrealy low dust lost from Biomass furnace.
  • Two stage gas combustion for low NOx
  • Two stage flue gas condensor for high efficiency

The plant is operting unmanned and provide Sønderborg with clean – CO2 neutral energy.
